Speciication of Letters Patent.

Patented May 11, 1909.

Application tiled October 16, 1908. Serial No. '1157,971.l

erated by the raising and lowering of the` closet seat, water being received in a tank from-a source of supply when the seat is pressed down, andreleased from said tank to yflush the bowl when the seat is free from pressure;

Another purpose. of the invention is to improve upon the construction of Water closet valves shown and described in Letters Patent granted to me August 20, 1907, No.

863,977, to the extent that thevalve is matori-ally simplified and is made to automatically establish communication between a source of water supply and a storage tank, when the'closet is occupied, and wherein,

when 'the closet is unoccupied, the supply of water to the storage tank 1s cut oif and the water stored in said tank is freed, for ushing purposes.

The invention consists in the novel con-- struction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompany-- ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures, and in which? f F igl'lre 1 is a vertical section through'la water-closet bowl, the improved? valve and the flushing tank, illustrating the valve in position to admit of flushing the bowl; lFio. 2 is an enlarged transverse section throng the valve mechanism, taken practically on the line12'2 of Fig. 3; Fig.' 3 is an enlarged verticalsection through a portion of a closet bowl and a sectionthrou h the' valve mechanism and tank, illustrating-the position of they valve mechanism when the, closet seat is under pressure, water being admitted to the storage tank but cut oilq from the bowl; and Fig. 4 is an enlarged vertical' detail section taken practicallyon the line 4-'4 of Fig.' 3a

.Ai represents a 4wate'1"closet bowl of any desired character, the particular bowl illus# trated being provided with a vent chamber 10, that receives water from a source of supply and delivers the same to the bowl A, when re uired, but the valve mechanism' to be dlescri 'ed may be applied to any type of bow The valve mechanism is operated through the medium ot' a hinged seat B, normally 'held from contact with the bowl A by a spring hinge B or springs of any suitable character. As is illustrated'in Fig. 1, the said seat B is provided with a=.downwardlyex tending linger l1, that opera-tes -u on the valve rod .or stem, to open the va ve to a storage tank, when the seat is occupied, and which, when the seat is unoccupied, permits the valve to cut off communication-between the source of water supply and the tank, and to establish communication betweenA the tank and the water-closet lbowl for flushing purposes, the latter position being shown in Fig. 1;, and the former position in Fig. 3'.

The valve casing C extends into the bowl A through the vent'lO inthe construction shown, and out beyond the rearof the bowl. This valve casing is preferably made in three sections, an inner section 12, an outer section 13, and an intermediatesection 14.

-.The inner valve section 12 is tapering, being smallest at .its inner end, and extends from a point outside of the bowlathrough the vent chamber 10 into the bowl proper. rlfhe said inner valve section 121 is held in place by screwing thereon nuts 15 and 16, the nut 15 being shown as engaging the inner wall of the vent chamber 10, and the nut 16 as engaging' the outer face' of the bowl; but other or equivalentmeans may bel employed fosecuring said section in place. The said inner section 12 of the valve casing isprovided within the vent chamber 10, with a series of outlet openings 17 .sincethe valve casing .C is closed-at 4itsinner and outer ends; and the said vent`c`hamber 10 is ,pro-

vided with an: opening 18, through which water received in the vent chamber-is delivered to the bowl A. Y

Ajt the outer or larger end of the inner casing. section 12', a flange 19 is formed, that .receives a union 20, having a suitable packing' 211, and said union connects the' inner casing section 12 with the intermediate' cas'- ing' section" 1'4. The outer casing' section- 1B has preferably a` threaded connection 22 witlil the intermediate'casing section 14, and` is provided at its Aouter end with a remov# center with a tank D, of any desired shape, and said neckA able plug 23, having a chamber 24therein, as is best shown in F ig. 3.

The intermediate` section 14 of the valve casing C is of uniform diameter to that of the outer and larger end of the inner section 12, and is provided at each side of its partition, designated as 25 and 26.

'A valve stem or rod C passes through the valve casing C, and that portion 27 of said rod that passes through apertures 28 in the partit-ions 25 and 26 1s rectangular in cross section, so that the rod is held from turn.- ing; and between the partitions 25 and 26, apertures or openings 29 are made in the upper and lower portlons of the intermediate casing section 14. -These openings 29 are in direct communication with the neck D ofl a surrounds said intermediate casing section 14, as is shown in Fig. 3. The neck D of the tank D is held in place by means of a nut 30 screwed upon the central casing section 14 near one end and a flange 31 formed at its opposite end. A third partition 32 is formed in the intermediate casing sect-ion 14, between the partition 26 and the outlet end of said section, and in this partition 32, a

lare sized opening 32Et is'made.

rubber gasket 33 is located at the outer face of the partition 25, having a suitable openin therein corresponding to the opening 28 in said partition, and said'gasket conflow from` the tan stitutes a valve seat, and a corresponding washer or gasket 34 engages the inner face of the partition 32, having a corresponding opening, as is shown in Flg. 3, and this latter gasket constitutes a second valve seat. The washers or gaskets 33 and 34 may be made of any elastic or yieldi material.

The stem or rod C is provi ed preferably with an integral valve 35, adapted to seat itself at the opening in the gasket 34, and a second valve 36 is screwed or otherwise detachably located on said rod or lstem adjacent to its outer end, adapted to seat itself at the opening in the outer gasket 33, as is ,shown bestin Figs. 1 and 3.

A sprin` 37 is coiled around the outer end portion o t; e valve stem or rod C', having 4bearing ther on at one -end and against the cap nut 23 at its opposite end entering the chamber 24 insaid nut.

'The seat B, being unoccupied, the spring 37 acts vto close thefvalve 36 land open the Valve/35, cutting ol the supply of water to the tank D', and permittin the Water to tothe owl A, as is shown in Fig. 1.

Water is received inthe outer section of the valve-casing C through a pipe 38, connected with any source of water supply, and

illustrated in Fig."3; and at Such time the sure on the valve 36 assists the' spring 37 in seating said valve. It will also be understood that the valves are metallic, while the seats are made of rubber or sinilar substance, which is an opposite arrangement v from that usually adapted.

One of the particularly novel features of the inventionresides in the neck D of the tankD, surrounding the inlet valve and its seat, and'also surrounding the intermediate or main portion of'the valve casing C, with the result that, lshould there be any leakage in the .valve casing, the leakage will be Within the tank D', and will therefore not prove a nuisance. lThis arrangement alsoltends to economy in construction.

Having thus described my invention; I claim as new and desire tosecure by Letters Patent 1. In a flushing valve for water closets, a valve casing having an inlet chamber, an outletchamber and an intermediate'chamber, a receptacle, communicating with the intermediate chamber, a source of water supply connected with the inletA chamber, apertured partit-ions in the intermediate chamber, valve seats carried by said partitions, a member movable in the casing, valves carried by Said member for engagement with said valve seats, and means for operating the said valve-carrying member, vto supply said receptacle and discharge the same. t v
